Mad as a hornet
You’re so mad you could probably punch a dragon. Hornets are like tiny angry dragons, and this person is their boss.
My sister stole my phone. I was mad as a hornet and told her she was a thief.
I got grounded. I was mad as a hornet and yelled at my brother for no reason.
My dog barked at me for an hour. I was mad as a hornet and took my dog for a walk in the middle of the night.
